The Golf Blog says: 2nd round leader Dustin Johnson faltered to a 75, slipping to -7 as the rest of the field went low at St. Andrews with soft greens and no wind at all. Jordan Spieth got himself into position for the third leg of the Grand Slam by finishing at -11. But the story of the day was amateur Paul Dunne tying for the lead at -12 with Louis Oosthuizen (who won at St. Andrews the last time the British Open was played here) and Jason Day. The leaderboard is jam packed with the likes of Paddy Harrington, Retief Goosen, Sergio Garcia, Justin Rose, and others.

Meanwhile, Dustin Johnson is 5 strokes back of the leaders with 16 players ahead of him, 7 of whom are major winners. It’s going to be a tall order for DJ to get his first major after today’s debacle.
